Stephen;

In theory the deco savings could be substantial because of the setpoint. What setpoint deco ignores is the cumulative impact of high ox exposures on blood gas interface and deco efficiency. Ask anyone who's been on a chamber ride what really high ox exposure feels like and you get the idea. One reason WKPP gives for the fact that they deco out of what are essentially sat exposures well inside any model's curve is the efficacy of toggling between low and high ox. You don't do this using setpoint CCR.

That aside, John was making the point that the profiles typically pulled by CCR divers out here raise the question about true practical benefit from CCR over O/C in the first place. There are circumstances where the added complexity and risk of RB's are justified. His point was that a 30 minute dive on the Olympic/Yukon/pick 'em doesn't qualify as such.

I wouldn't assume that because he doesn't dive an RB that John's ignorant of how they work and the risks involved. It may be he doesn't dive one precisely because he understands those issues.
